I have a all stock 1977 440 casting# 4006630 really low mile and runs great in my 67 polara but its time too pep it up a touch. Im looking at ordering a set of eddie heads but unsure which to go with. I belive the factory heads are 452 open chamber. With head swap id like to bump the compression up to 10-1.can i go with a set of closed chambers or do i need too stick with open. Eddie has 5 diff models the E streets 1 with 77 cc and 2nd with 84cc and then the Performer rpm's with 75cc, 84cc and 88cc. I am also thinking of running the performer rpm intake and still debating cams. I have on hand a summit 6401 but i would like a lil more lope so you can hear the cam. This is going to be a cruiser thats able too open a can of whoop *** when needed. TIA looking forward to the ideas.
